The slime mould is a bright yellow amoeba that possesses primitive intelligence, problem solving skills and memory. It is highly efficient at forming networks between given points and has been used to map the worlds' transport networks, migration routes and desire paths, most notably in 2010 it accurately replicated the Tokyo rail network. It is also quite beautiful, the branching patterns reminiscent of forms seen at varying scales within nature, from blood vessels to tree branches, from river deltas to lightening flashes. It can learn about its environment, remember where it's been and navigate through complex territories - all without any sensory organs and no brain.
Using the historical and contemporary topography of Berlin as inspiration, we propose a series of experiments and activities, which explore collective communication, cooperation and navigation at different scales - in slime mould and in humans!
These organisms offer intriguing models to examine collective behaviours: how ideas spread, how group decisions are made, and how communities cooperate. We want to use the slime mould as a model to look at human systems - urban, social and cultural - exploring how people interact and respond to their environment, how they gather and distribute information. We want to create a platform for exploring alternative ways of seeing and behaving, individually and collectively.
The aim of Swarm | Cell | City was to create the conditions for critical and creative learning to take place, without trying to control the outcomes. By using participatory arts and performance practices to explore the creative potential for bio/social models, we hope to create a collective 'system of enquiry' with everyone as co-creators. Through the workshops participants learned about slime mould intelligence, create annotated maps capturing observations of city exploration, constructed experiments for slime mould growth, devised their own city explorations, and engaged in collective performance experimentation.
The origins of the creative exploration derive from self-organising principles in natural phenomena, for example using stigmergic processes. Stigmergy is a mechanism of indirect coordination, through the environment, between agents or actions. The principle is that a trace left in the environment by one action stimulates the performance of a subsequent action. In this way, actions reinforce and build on each other, leading to the spontaneous emergence of coherent, apparently systematic activity. Ants leave pheromone signals, slime mould leave membranous trails, termites leave mud balls - all communicating to others important information about environmental conditions. These processes formed a basis for creative improvisation and communication between humans in an urban environment.
Heather Barnett is an artist, researcher and educator working with natural phenomena and biological design, often in collaboration with scientists, artists, participants and organisms. Utilising living materials and imaging technologies, her practice explores how we observe, represent and understand the world around us. Projects include microbial portraiture, systems modelling, and an ongoing 'collaboration' with an intelligent slime mould, Physarum polycephalum. As one of the world's largest single-celled organisms, the slime mould possesses a skilful ability to solve spatial problems and learn from interactions with its environment.

plan b is the artist duo Sophia New and Daniel Belasco Rogers. Since 2003 (Daniel) and 2007 (Sophia), plan b have recorded and stored every daily movement using GPS technology. Results of this are presented in festivals, galleries and at http://planbperformance.net. In their performance work, they explore topics such as the dynamics of conversation, singing, confessions and cycling. They also work in the fields of installation, new media, fine art and give workshops. Since the establishment of plan b in 2002, they have developed more than 25 projects, which have been and are to be seen in over 27 cities worldwide.
